Abstract
A purpose of the present invention is to quickly change a focal point of a laser emission system so that processing with high quality and good processing efficiency can be performed. In a laser processing apparatus including: a laser oscillator configured to output a laser pulse; a laser deflector configured to deflect the laser pulse in a two-dimensional direction; and a controller configured to control the laser oscillator and the laser deflector, the laser processing apparatus being configured to emit the laser pulse to a workpiece for processing the workpiece, the laser processing apparatus has a feature in which an electrooptic device capable of, under control of the controller, electrically changing a focal point of the laser pulse to be input to the laser deflector is arranged in an input side of the laser deflector.
